Spec sheet

Purpose

Nexus is a collection of tools for streaming visualization of large 3D models in OpenGL using C++ and JavaScript.Read 8 Oct 2026 · vcg.isti.cnr.it

Intended users

The product is for developers integrating multiresolution 3D visualization into C++ or JavaScript engines and for users preparing models for web viewing.Read 8 Oct 2026 · github.com

Integrations

The project provides a WebGL library, a Three.js loader and a rendering engine for the 3DHOP open-source framework.Read 8 Oct 2026 · vcg.isti.cnr.it

Support

The project page acknowledges support from VCG, the Informatics Department at TU Clausthal and 3D-COFORM.Read 8 Oct 2026 · vcg.isti.cnr.it

Headquarters

Maker

The Visual Computing Lab is a research group at CNR-ISTI in Pisa, Italy.Read 8 Oct 2026 · vcg.isti.cnr.it

Conversion

Nxsbuild converts .ply or .obj input models into multiresolution .nxs models.Read 8 Oct 2026 · vcg.isti.cnr.it

Conversion inputs

Nxsbuild generates multiresolution .nxs models from .ply or .obj files and can join multiple model pieces into one .nxs file.Read 8 Oct 2026 · vcg.isti.cnr.it

Downloads

Source code and Windows executables are available from the Nexus GitHub releases page.Read 8 Oct 2026 · vcg.isti.cnr.it

Editing

Nxsedit can compress, prune lower hierarchy levels, export to .ply, and report model information.Read 8 Oct 2026 · vcg.isti.cnr.it

Large models

Its out-of-core tools process and visualize large models and textures with limited resources.Read 8 Oct 2026 · vcg.isti.cnr.it

Licensing

The maker's repository says the C++ software is free under GPL and the JavaScript software is free under MIT; it also notes dependencies on Qt and VCG lib.Read 8 Oct 2026 · github.com

Model editing

Nxsedit can compress, prune or export a model to .ply; the page says compression can reduce model size to 10–20%.Read 8 Oct 2026 · vcg.isti.cnr.it

Multiresolution

It converts 3D models into a structure that supports view-dependent resolution.Read 8 Oct 2026 · vcg.isti.cnr.it

Resource limit

Nxsbuild's RAM option defaults to 2000 MB, and the maker warns it is not a hard limit.Read 8 Oct 2026 · vcg.isti.cnr.it

Streaming and compression

Nexus streams models over a network and uses the Corto algorithm for compression and fast decompression.Read 8 Oct 2026 · vcg.isti.cnr.it

Supported geometry

Nexus supports point clouds and meshes with per-vertex normals, colors and texture coordinates, and stores textures internally.Read 8 Oct 2026 · vcg.isti.cnr.it
